Transformation Designer - element parameters - source

The source element defines the location of input data. Attributes on the source specify whether the value from the source should be passed to the target and whether the source data should be iterated over.

<source does-for-each='yes|no' passes-value='yes|no'>

		data path

</source>

Parameters

does-for-each (optional)

Specifies whether the data path should be processed many times, as if in a 'for-each(data-path)' loop. See the remarks below for more information on this parameter.

passes-value (optional)

Specifies if the value of the data referred to by the data path should be passed to the output. See remarks below for the default value of this parameter.

data-path (mandatory)

Provides the fully qualified data path into the input data. For example, if the input data looked like this:

<data>

  <purchase-order>

    <date>10101999</date>

  </purchase-order>

</data>

The fully qualified path to the date would be 'data/purchase-order/date'.

Remarks

The does-for-each and passes-value attributes are optional. If either are omitted a default value is used dependent on whether the data pointed to by the data-path has any child elements.

has children: for-each = yes, passes-value = no

does not have children: for-each = no, passes-value = yes
